Cloud Computing Federation is a main trend of Cloud Computing. Resource Management has significant effect on the
design, realization, and efficiency of Cloud Computing Federation. Cloud Computing Federation has the typical
characteristic of the Complex System, therefore, we propose a resource management architecture based on complex
network theory for Cloud Computing Federation (abbreviated as RMABC) in this paper, with the detailed design of the
resource discovery and resource announcement mechanisms. Compare with the existing resource management
mechanisms in distributed computing systems, a Task Manager in RMABC can use the historical information and current
state data get from other Task Managers for the evolution of the complex network which is composed of Task Managers,
thus has the advantages in resource discovery speed, fault tolerance and adaptive ability. The result of the model
experiment confirmed the advantage of RMABC in resource discovery performance.
